Rescued from a garage sale and spent precious time bringing it back to what is extremely close to new condition without changing a single peice of originally bought watch except installing NOS factory bulova new crystal.

I agree with Geoff, that sweep second has been shortened, and points to a dial mod.

Likely the minute hand is canted upward, so the sweep would bind with it and/or touch the crystal. I see many watches where the hands have to be very carefully contoured because of indices or stones added.
